Current description of the compatible property for at24 is quite vague. State explicitly that any "<manufacturer>,<model>" pair is accepted as long as one of the listed strings is used as fallback.

I read the above as if it is no longer allowed to have a plain old atmel chip, since the atmel compatibles are now valid as fallbacks /only/. I don't think that's what you intended? Cheers, Peter
